It's sultry and I have a headache. What if I don't want to go to work? I have no strength at all. It's hard to ask for leave!

Ask for leave on the pretext of heatstroke. There are many reasons for heatstroke. If you work in a workshop with high temperature and poor ventilation, it is easy to get heatstroke. In agriculture and open-air operations, the direct exposure of the sun, coupled with the exposure of the earth, makes the atmospheric temperature rise again, making people's meninges congested and cerebral cortex ischemic, causing heatstroke, and the increase of humidity in the air is easy to induce heatstroke; In public places and families, people are crowded and concentrated, heat production is concentrated, and heat dissipation is difficult. Meteorological conditions of heatstroke The occurrence of heatstroke is not only related to temperature, but also related to humidity, wind speed, labor intensity, high temperature environment, exposure time, system strength, nutritional status, water and salt supply, etc. The factors that induce heatstroke are very complicated, but the most important factor is temperature. According to the meteorological characteristics, the microclimate of heatstroke site can be divided into two categories: one is dry and hot environment, which is characterized by high temperature, strong radiant heat and low humidity. Generally, the ambient temperature is 5- 15℃ higher than that outside, and the relative humidity is often lower than 40%. The other is a hot and humid environment, that is, high temperature and high humidity, but the radiation heat is not strong. Because when the temperature is 35-39℃, 2/3 of the body's residual heat is evaporated and excreted through sweating. At this time, if the surrounding environment is humid, sweat is not easy to evaporate. According to experiments, the conditions leading to heatstroke are: ① Relative humidity 85%, temperature 30-365438 0℃; ② The relative humidity is 50% and the temperature is 38℃; ③ The relative humidity is 30% and the temperature is 40℃. The degree of heatstroke can be divided into three levels: ① threatened heatstroke. In high temperature environment, sweating, thirst, dizziness, tinnitus, chest tightness, palpitation, nausea, limb weakness, inattention, and the body temperature does not exceed 37.5℃; ② Mild heatstroke. Have symptoms of threatened heatstroke, while the body temperature is above 38.5℃, accompanied by flushing, chest tightness, burning skin and other phenomena; Or wet and cold skin, vomiting, blood pressure drop, and rapid pulse; ③ Severe heatstroke. In addition to the above symptoms, syncope or spasm occurs; Or don't sweat, the body temperature is above 40℃. Hope to adopt, thank you.
